For packing or settling materials, use a vibrator with an impact force of (1.5) to 2 times larger than the weight of the

Vibration - Wikipedia

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.
